05
The design integrates elements of Latvian identity with modern architectural practices.

LIGO Tower, pronounced "Leeg-Wa" and meaning "Sway," serves as a notable structure in Latvia, designed to connect with the cultural traditions surrounding the summer solstice and the Jani festival. It combines practical use with symbolic meaning, bringing together the natural landscape and the deep-rooted customs of the Latvian people. The design reflects the balance of light and dark, incorporating two tree forms—Oak and Linden—into a unified structure that reaches upward.

Cultural Symbolism

The design communicates the strength and history of Latvian culture through its architectural form. The merging shapes of the Oak and Linden trees symbolize unity and resilience, representing the Latvian spirit. By integrating these elements from nature, the tower acknowledges the connection between the community and its surroundings. The winding paths within the tower facilitate movement and experience, guiding visitors through themes of life and the balance between opposing forces.

Dynamic Facade

The facade of LIGO Tower features kinetic and translucent polycarbonate panels that respond to the wind. This choice allows the structure to sway gently, creating a relationship with the environment. As light passes through these panels, it creates a changing internal atmosphere. Visitors experience shifts in illumination as they move through the space, making the journey feel alive and engaging.

Central Bonfire Element

At the top of LIGO Tower, a glass-enclosed area surrounds a central bonfire, symbolizing the "fire in the sky." This element connects directly to the traditions of the Jani festival, where fire represents rebirth and fertility. The design enhances the visual aspect of the tower while encouraging community interaction. Gathering around the bonfire provides a communal space, and the panoramic views from this location deepen the connection between visitors and the landscape.

The design balances natural shapes and structural form, offering a path that rises toward the sky. The varying heights and gentle curves of the steel elements reflect the growth found in nature, while the translucent panels unify the natural and built environments. The tower tells a story of Latvia’s cultural identity, inviting a connection to both history and the present.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
